Product Description

Edible oil refinery technoloLD:

Oil refining is based on the difference of oil and the impurities in the physical and chemical properties, separate the grease and impurity by some technical ways, in order to improve the oil edible, storage stability and safety process, suits different kinds of vegetable oil process, Oil refining process is divided into batch, continuous refining according to the raw materials and capacities.

There are two kinds of refining method chemical and physical and the product oil can reach first to fourth grade with lowest cost.

Capacity: 5TPD--1000TPD

Main procedure

Deodorization tower

Vacuum stripping deodorization: The peculiar smell impurity and oil have different volatility. Under the condition of high temperature and high vacuum, let the peculiar smell impurity stripping with steam to deodorization.

Semi-continuous physical refinery

Its called bleaching,dewatering pot, its used to remove water from oil by vacuum. The bleaching earth is breathed into bleaching pot, after stirring; the bleaching earth is filtrated by filter, so the color of the oil is changed.

Degumming

This is the most important section of hydrate de-gumming, manage the adding water (there is a little P-acid in the water) amount, temperature and add water speed, usually water adding amount is about 3 times of phospholipid content, that is 3-10% oil weigLD, water temp needs to be higher than oil temp.

Decolorization

In normal situation , there is pigment in the crude oil , we need to using the active clay to absorb the pigment away , after 20 mins , we use the vibrating filter to filter the waste clay away . If you want to get ligLD color oil , you need to add more active clay . That is mean , the customer can accord to his requirement to control the oil color. This process is carried out under the vacuum condition.
